That's the stuff looking like random memory that I talk about above...
If you look at it closely, it's actually not random memory. At least in
the first 2 failing tests which are not obfuscated by aggregates on top
of aggregates. It looks like first NumericDigit is ok and the second one
is corrupted (there are only 2 NumericDigits in those numbers). Of
course the conversion to Numeric is done from the end so it looks like
only the last computation/pointer change/something stays ok while the
rest got corrupted.
Would this mean the bug is most likely somewhere in
int128_to_numericvar()? Maybe that version of gcc has a bug in some
__int128 operator or I messed up the code there somehow.
